Описание

This method builds a SQL statement using autoPrepare() and then executes the statement using execute() with it.
Parameter
-
string
$table -
name of the table
-
array
$fields_values -
assoc (key => value), keys are fields names, values are values of these fields
Values are automatically escaped and quoted according to the current DBMS's requirements.
-
integer
$mode -
type of query to make (DB_AUTOQUERY_INSERT or DB_AUTOQUERY_UPDATE)
-

Пример
Using autoExecute() in insert mode
<?php
// Once you have a valid DB object named $db...
$table_name = 'user';
$fields_values = array(
'id' => 1,
'name' => 'Fabien',
'country' => 'France'
);
$res = $db->autoExecute($table_name, $fields_values,
DB_AUTOQUERY_INSERT);
if (PEAR::isError($res)) {
die($res->getMessage());
}
?>
Using autoExecute() in update mode
<?php
// Once you have a valid DB object named $db...
$table_name = 'user';
$fields_values = array(
'country' => 'France',
);
$res = $db->autoExecute($table_name, $fields_values,
DB_AUTOQUERY_UPDATE, "country = 'Japan'");
if (PEAR::isError($res)) {
